摘要： A facsimile apparatus comprises a receiving buffer for receiving video data, a scanner for reading an image, a VRAM for storing a coded data, a single coding/decoding (C/D) IC for MR-coding, MR-to-MMR coding, decoding, and error-checking, and a page printer, and a control circuit, when an event requiring more than two operations of the C/D IC at the same time, the control circuit permits only one operation and force the other operations to wait in some condition. In another condition, the control circuit permits one of the other operation and force the other operations to wait. For example, when the scanner reads an image to produce read data and the C/D IC codes the read data to store the read data in the VRAM and there is a call, the control means connects the line but keeps the coding if the receiving buffer has a space. In the presence of the space the control circuit interrupt the coding and starts the decoding. Another event requiring operation of C/D IC of the MMR coding from MR coded data and operation of MR coding, decoding, or error-checking may be occur. Various events requiring combination of operations of the single C/D IC at the same time and various adaptable controllings are considered.
